1. A bio is charged according to the direction, if we put the reads
and sync writes together, we need to search the queue to pick a
certain number of read and write IOs when the limit is not reached.

Ah, you're right.

2. I found that the multi-queue scheduler kyber also has three queues:
one for read, one for sync write and one for others. This patch
introduces another queue for async writes and others just like kyber.

Yeah, it'd make sense to make that a separate queue then.

Could you please review this patch and give some advice?

Thanks.
